The present invention relates to new and useful I improvements in corn pickers, and has for its primary object to provide, in a manner as hereinafter set forth, a machin of this character which is adapted to be expeditiously mounted-for operation on one side of a conventional tractor, motor truck or wagon.

Another very important object of the invention is to provide a corn picking or harvesting machine of the aforementioned character which embodies a unique construction, combination and arrangement of endles gatherers and snapping and husking rolls. Other objects of the invention are to provide a corn picker of the character described which willibe comparatively simple in construction,

strong," durable, highly efficient and reliablein use, compact, light in weight, and which may be manufabturedat low cost All of the foregoing andv stillfurther objects and advantages of the invention will become aD-' parent from a study of the following specification,

taken in connection with the accompanying draw- I ings wherein like characters of reference desig--- nate corresponding part throughout the several viewaand wherein: v

Figure l is a view in side elevation with a portion' broken away, showing acom picker constructed in accordance with the present inventionlmounted for operationion, one side of a motor truck.

Figure 2 is a top plan view thereof. Figure3 is a plan view of the snapping and husking rolls. I a 1 Figure 4 is a sectional view taken on the line 45 of Figure 2.

Figure 5 is aview showing the drive for the ping and husking rolls. V

Figure 6 is a fragmentary vi'ewin elevation ofone ot the rolls and the adjacent conveyor, looking at the inner side thereof.

Figure 7 is a sectional view taken on'the line 7-7 of Figure 2.

Figure 8 is a vertical view taken on the line B-8 of Figure 1.

, Referring now to the drawings in detail, it will be seen that reference character I designates generally an elevator. In the embodiment shown, in Figures 1 and 2, of the drawings, the elevator I is mounted at an inclination on one side of the body 2 of a motor truck 3 in any desired conventional manner as through the medium'of one or more suitable hangers 4'. A hange; 4' prime may take the form as best shown in Figure l of a substantially L-shaped member, the upright leg of 2 which terminates ina hook to overlie the top edge of the truck body 2.

The elevator I includes a pair of spaced, par- 1 allel, elongated, metallic housings 4 of substan- 5 tially segmental cross-section, which housings are mounted on aframe structure 5. Pairs of spaced, parallel guides 6 are mounted in the lower, inner portions of the housings 4. Slots 1 in the inner walls of the housings 4 communicate with themner guides 6;

Sprocket wheels I are journaled in the housings 4 adjacent the ends of the pairs ofguides 6.

Endless conveyor chains 8 are operable in the guides 6 and trained over the sprocket wheels 1'. Flights 9 are mounted at suitably spaced points onthe chains 8. The upwardly moving flights 9 travel in the slots I and project between the hous- I ings 4. These flights, it will be observed, are staggercd and overlap when moving upwardly, as il- 2c lustrated to advantage in Figure 4 of the drawings. The endless chains 8 may be driven in any suitable manner. If a power plant is to drive the endless chains 8, a platform I0 for said power plant is suspended beneath the elevator I.

25 Journaled in the frame structure 5 between the housings 4 is a pair of coacting rolls II. Each of the rolls I'I includes a metal front snapping section I2,"a metaliintermediate husking section I3, and a rubber rear husking section I4. The snapping and husking rolls I I it will'beobserved, are

below and adjacent the upwardly moving flights 9.

Gears I5 between the sections I2 and I3 connect the rolls II for operation inunison in opposite directions. A plate I 6 is mounted above the gears I5. A gear II on a shaft I8 drives the adjacent gear I5. The shaft I8, is geared to a transverse shaft I9. A sprocket wheel is loosely mounted on the shaft I9. A sprocket chain 2| is trained over the sprocket wheel 20 and a comparatively large sprocket wheel 22 on the adjacent rear wheel Y 23 of the motor truck 3. A clutch 24 which is' splined on the shaft I9 is adapted to'releasabl'y connect the sprocket wheel 20 'to said shaft.

,A forked lever 25 on the inner side of the elevator I engages and disengages the clutch 24. An actuating rod 26, operable from the drivers compartment 21 of the motor truck 3, is con-J nected to the lever 25. v

' A, bracket 28 is removably mounted on the front portion of the vehicle body 2. Mounted on the bracket 28 is a toothed ring 29. A reversible I hand lever 3|] is journaled onthe ring 29,- the latch' 3| of said hand lever being engageable with the toothed periphery of said ring for releasably 55 securing said lever in adjusted position. A link 32 connects the hand lever '30 to a bracket 33 I on the adjacent portion of the elevator l for raising andlowering said elevator. As best seen in Figure 8 of the drawings, the bracket 33 is coupled to the lower end portion of the link 32 by a pin and slot connection 34. Thus, the forward or lower end of the elevator i' may have limitedupward movement independently of the lever 30. Such movement is yieldingly resisted.

by a coil spring .35 on the link 32. Ground shoes 36 are provided on'the lower end of the elevator I.

Projecting rearwardly from the upper portion of the elevator I is a bracket or the like 31'. A

- bowl or other receptacle 38 is rotatably mounted on the bracket 31 for receiving the ears of corn from the elevator l. Projecting from the rotatably adjustable receptacle 38 is achute 39. for

discharging the ears into the body 2, or, if desired, into a vehicle accompanying the picker. It is thought that the operation of the machine will be readily apparent from a consideration of the foregoing. Briefly, the inclined elevator l straddles the row to be harvested and the stalks are directed into said elevator by the outwardly curved snout portions 40 on the forward ends of the housings I. The sections l2 of the rolls ll snap the ears of corn from the stalks, .which ears are carried up said rolls by the flights 9 on the endless chains 3. The husksare removed by the sections l3 and ll of the rolls ll. Whenthe husked ears reach the-upper end of the elevator I, they are dropped into the receptacle 38 and discharged by gravity through the chute 33 into the body 2 of thevehicle 3. In Figure 1 of the drawings, also Figure 2, the hand lever 30 is operable from the driver's compartment of the vehicle.

and the removable bracket 23 mounted in the If desired, this lever may be reversed position shown in dotted lines in Figure 1 of the drawings, whereby said lever may be conveniently operated from within the body 2 for the purpose of raising or lowering the forward end of the elevator.
